There's a slight issue in that mod, in that if you pass a string as the 'page' parameter it becomes page 0 and generates a starting LIMIT in the query of -20 which is invalid (first page is 1 so 0 is invalid). But that doesn't create a security issue, and even if it did allow you to modify the sql, putting a file name there wouldn't read the file. So I don't think you have anything to worry about.
BTW, the ip address in the above error is mine, so please everybody don't start banning me.
